Where I live, and I suspect in most locations, a new circuit
requires a new permit. A subpanel certainly does.

I asked an electrical inspector (from whom I had just taken a home
electrical course) what was involved in getting a new transfer switch
inspected. He said that no one would get something as simple as a transfer
switch inspected; inspections were only for major projects. In the course
he said that technically changing a light switch requires an inspection, but
that it is never done. In order to affect your insurance (after a fire) the
insurance would have to prove that the uninspected work caused the fire, and
that the work was done negligently; a tall order.

I fretted a bit about the transfer switch, as it was my biggest project to
date; but decided that the worst that could happen would be an open
connection. Even if a hot connection broke and caused an arcing short, it
was all in a metal box with no combustibles in the box; so what could
happen? Sure, you can come up with crazy things like an open neutral
combined with a short in an appliance, but realistically not much can
happen.
